Beit known that I, HIRAM B. MORRISON, of LeRoy, in the county of Genesee, .and State of New York, have invented a certain new and useful Improvement in Nozzles for Hose and Water-'Discharge Pipes; and I do hereby declare that thefollowing is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification. p I

Figure 2, a cross-section, in .plane of line x z, iig. 1.

`Figure 3, a perspective view of one of the spiral wings.

Like letters of referenceindicate corresponding parts in allthe figure.

I obtained Letters Patent, dated October 14, 1862, No] 36,688, and August 25, 1863, No. 39,700, forimprovements in nozzles for hose and water-discharge pipes, the general featuresof which are embodied in my present improvement. i

This invention consists in the employment of spiral wings, situated inside the waterpassage',-for the purpose of imparting to thejointed t-ip arotary motion; the said vvings being capable of being adjusted to different positions, to regulate the motion of the nozzle to distribute the water, and turning back out of the way when not required for use.

The invention further consists in the special arrangement of parts as hereinafter set forth.

I In the drawings, A represents the sleeve, to which the hose is attached; B, the thimble, fitting inside of the sleeve, and 'screwing in the end'of slecve C, in such a manner asto'form aswivel-joint; and D is thetip, which is jointed obliquely to thenozzle at b. This arrangement' is similar to my patented inventions above referred to. Y v

The spiral wings F F,l which turnpacross the water-passage, are provided at one end with straight bearings, c c and at the opposite end with right-angled hearings, dil, which rest in corresponding recesses ef, formed in sleeve C. The wings are secured in place by means Aof screws g 7L, resting inside the bearings c d, when screwed together. v I l The arms z' ot" bearings d extend through openings o o in sleeve C, their ends resting in sockets c c in the adjustable turningring Z.y This ring Z rests dagainst shoulder mand is secured in place by nut n, which is screwed on the end of sleeve C, up against thevadjustable ring, and held. in position by set-screw r.'l Theringl is provided \vitl1 oil`set's t t, to prevent the hand from slipping when being adjusted. v v v indicate the several packings necessary in closing the joints. A

The operation will be readily understood. The water, in passing through the nozzle, strikes the spiral wings F F, (set across the passage,) and actsupon them in a manner similar to water on a. water-wheel, imparting to the whole nozzle a 'revolving motion in sleeve A, and distributing the water from tip D in a circle.

` By simply turning the ring Z, I am enabled to adjust the turningmotion of the nozzle exactly as'desired, whether the pressure be great or small. If it is great, .the wings are set but a little way out, land if small, they may he set square acrossfto receive the greatest impetus; or, when not `:required forl use, they may be turned back into recesses s s, (shown in dotted lines, iig. 2,) entirely out of the way. This adjustmentvis of very great importance. I y

Bythe employment of thisarrangement, I am enabled to give'a'positive rotary motion to a nozzle having but a single tip, an effect that cannot be accomplished properly by the angular nozzle alone. By inserting the nozzle through a hole in the wall, the rotary motion will-deluge everypart of a room, without opening the doors or windows tovincrease the hre. A u 4 The arrangement of: the tightening-nut n, in connection with the adjusting-ring l, is of importanoe in holding the wingsin position against the varying pressureof the water. Y

Under very heavy pressure, the tendency of the wings is to close, whicl' is remedied by simply tightening upnut n. l t

vWhat I claim' ns my invention, anddesire to secure byLettere Patent, is-

1. The arrengement,inside the bent nozzle D, of the spiral wings F F, adjustable to diiierent positions across the water-way, and capable of being xed in place, and operating to impart e. rotary motion to the nozzle by the current passing through, in the manner and for the purpose specified.

2. The arrangement, in connection 'with the spiral wings Fvo'f the elbow-arms d z', resting in the turningring l, which is tightened in position by nut n, the whole as hereinset forth. A

In witness whereof, I have hereunto signed myname in the presence of two subscribing witnesses.
